[Chronic Chagasic Cardiomyopathy at the Hospital General de Zona no. 24 IMSS. Poza Rica, Veracruz].

Unlabelled: Northern Veracruz has conditions, biotic and abiotic, to support Triatomine bugs and vectorial transmission of Trypanosoma cruzi to human beings. Therefore we explore seroprevalence of antibodies to this parasite and the presence of Chronic Chagasic Cardiopathy (CCC) at Cardiology ward in a General Hospital serving North of Veracruz State, and neighbord states Hidalgo, Puebla San Luis Potosi and Tamaulipas.

Material And Methods: We search for consecutive adult patients attending outpatient and beds assigned to Cardiology between March through September, 2003.

Serological and parasitological screening of Trypanosoma cruzi infection in mothers and newborns living in two Chagasic areas of Mexico.

Background: Maternal-fetal transmission of Trypanosoma cruzi generally occurs in 2-12% of pregnant infected mothers. This transmission form has been poorly studied in Mexico where only one case of congenital infection published in 1998 has been reported.

Methods: We screened 145 mothers and their delivered babies in two hospitals of endemic regions in Mexico (states of Chiapas and Veracruz) searching for anti-T.

[Epidemiological and clinical outlook of chronic Chagas' heart disease in Mexico].

Objective: To compare the epidemiological and clinical characteristics of chronic Chagas' heart disease to other dilated cardiomyopathies.

Methods: A study comprising 128 patients from a heart disease center was carried out from 1993 to 2003. Of them, 51 (40%) were Trypasonoma cruzi positive.
